Wake Frequency Calculations

Specialist thermowell testing ensures the highest possible degree of safety.

We use proprietary software to calculate the Wake Frequency of a Thermowell to the latest ASME 19.3 TW Standard.

H&B’s Wake Frequency Testing has three main improvements over older standards: by taking into account stem profiles, and using more accurate natural frequency equations, our tests better reflect real-world conditions; the Strouhal number—used to calculate the vortex shredding rate—is properly calculated; perpendicular and inline oscillation are now considered.
